Time Domain Reflectometry is the analysis of conductor lines (interconnects)by sending a pulsed signal into the conductor and then examining the reflection of that pulse. A TDR transmits a short rise time pulse along the conductor. If the conductor is of a uniform impedance and is properly...
The following attached file contains an SSH Client extension
which I made for my own use, but it may also be useful for users of the MIT Application Inventor 2 (AI2) community, or even to the AppyBuilder community (code intrinsically compatible for the last one, but not tested). This is just the...
In this blog post i will share the OLED libraries with you, which are written for mikroC compiler and can be used with any other C compiler.
Following are the functions which are currently present.

Find bellow an Android TCP client extension
that implements a very simple socket; note that its operation is performed 'one-shot', which means that only one command is sent ( and its respective response, read ) at a time, and then the socket connection is closed. So, be aware that it is not a...
Spring-loaded pins are rapidly finding new applications in modular product design. Also referred to as SLCs (spring-loaded connectors), this product resolves many of the manufacturing issues like misalignment, coplanarity, and tolerance stack up that can plague traditional pins and sockets...
When I was in Class Five, my father gave me a book on Basic Electronics and a trainer board made on wooden board with Breadboard pasted on it and with power supply incorporated and told me to play with this book and trainer board instead of Computer game. I started to learn Analogue electronics...
Simple I/O Decoding and Interfacing Using PLDs:
Programmable logic is particularly useful for decoding the addresses and
control lines from a processor, because it can be used to activate the chip
enable signals for the various memories and I/O chips in a system. PLDs are
more flexible...
CHALLENGES:-

LINE FOLLOWER ROBOT
Hi everyone, recently I have created a line follower project, me and my couple of best friends, Creating this Line Follower Robot was not so easy, trust me I have spent many early mornings and couple of sleepless nights, I believe in hard work, I’ve won numerous awards for...
hi friends,
programming of micro controller in assembly takes more time than it in c,but for the assembly lovers its easier to make the programming more friendly by means of the use of macros;
just see the example
in 8051 assembly programming when we are interfacing an LCD
it is necessary to...

Few days ago I was just trying to familiarize an 89C430 microcontroller. I am using SDCC in linux. Then I feel the process of hex loading (ISP) a bit difficult since I need to type the commands and send the hex file using a terminal emulator. Then I wrote a small python script (pyserial based)...
I am working on my final year project "RFID based Access System"..
Here's the code to interface the LCD with 89C51..

Some compilers may have built in functions for these convertions, but others don't. Below are two functions for converting a BCD number to decimal and vice versa:
#define uint8 unsigned char
uint8 BCDToDecimal (uint8 bcdByte)
{
return (((bcdByte & 0xF0) >> 4) * 10) + (bcdByte & 0x0F)...

The atmega has a few different PWM modes, the frequency and duty ratio depend on the mode and values used, this is a description of the way to calculate them.
In fast PWM top=ICR1, the output PWM frequency=timer clock/(ICR1+1) and the duty=OCR1A(B)/ICR1
In fast PWM top=0h00ff, the output...
